"All right," I said. "We are coming right up, Parks. Good-bye," and I hung up and slipped into my coat.

Then, as I took down my hat, a sudden thought struck me.

If the unknown Frenchman was indeed an emissary of Monsieur X., Madame might be acquainted with him. It was a long shot, but worth trying! I stepped to my desk, took out the photograph which Godfrey had given me, and slipped it into my pocket. Then I hurried out to the elevator.

CHAPTER XIV

THE VEILED LADY

There were three persons in the carriage. Mr. Hornblower sat with his back to the horses, and two women were on the opposite seat. Both were dressed in black and heavily veiled, but there was about them the indefinable distinction of mistress and maid. It would be difficult to tell precisely in what the distinction consisted, but it was there. Mr. Hornblower glanced behind me as I entered.

"You spoke of a witness," he said.

"He is at the Vantine house," I explained, and sat down beside him.

"This is Mr. Lester," he said, and the veiled lady opposite him, whom
I had known at once to be the mistress, inclined her head a little.

Those were the only words spoken. The carriage rolled out to Broadway and then turned northward, making such progress as was possible along that crowded thoroughfare. I glanced from time to time at the women opposite, and was struck by the contrast in their behaviour. One sat quite still, her hands in her lap, her head bent, admirably self-contained; the other was restless and uneasy, unable to control a nervous twitching of the fingers. I wondered why the maid should seem more upset than her mistress, and decided finally that her uneasiness was merely lack of breeding. But the contrast interested me.
